Pregnant from sex before ovulation

m

So if clear blue advanced is wrong and I am going to ovulated tomorrow according to easy at home, do I still have a good chance if we don't have sex tomorrow because the whole world is coming to visit and stay at our one bedroom apartment because my cousin just had a baby lol 🤪 (today is January 28th Thursday, and tomorrow is January 29th Friday) and easy at home says o day is 1/29
